Compatible Replacement & Equivalent Models
When the 5X00226G02 is unavailable or end-of-life, the following models may serve as functional replacements depending on your system configuration. Always validate electrical and firmware compatibility before substitution:
- 5X00226G01 — Earlier revision of the same OCR 400 I/O interface card; verify revision compatibility with your controller firmware
- 5X00226G03 — Later revision; may include minor hardware updates; confirm backplane pinout compatibility
- Emerson Ovation I/O Modules — For full platform migration from OCR 400 to Ovation DCS; requires engineering assessment
- Third-party OCR 400 compatible I/O cards — Available from certified aftermarket suppliers; must meet original signal conditioning specifications
Contact support@konmask.com with your system details for a verified cross-reference recommendation.
Why Choose the Original Model
- Guaranteed backplane compatibility — Designed specifically for the OCR 400 rack architecture; no signal adaptation required
- Firmware-matched operation — Works with existing OCR 400 controller firmware without reconfiguration
- Proven field reliability — Validated in power generation, petrochemical, and heavy industrial environments
- Reduced commissioning risk — Drop-in replacement minimizes downtime during maintenance windows
- OEM traceability — Original units sourced with full documentation and test records where available
Typical Applications
- Power plant DCS I/O expansion and maintenance (coal, gas, nuclear legacy systems)
- Petrochemical and refinery process control signal interfacing
- Water treatment and utilities automation
- Pulp and paper mill control system maintenance
- Steel and metals processing plant DCS upkeep
- Spare parts inventory for OCR 400 platform lifecycle extension
System Compatibility
- Controller Platform: Westinghouse OCR 400 DCS
- Rack Type: OCR 400 series I/O rack (backplane-powered)
- Software / Engineering Tools: Compatible with OCR 400 configuration tools; consult your system integrator for Ovation migration paths
- Not compatible with: WDPF, Ovation (direct), or third-party DCS platforms without hardware adaptation
Selection Guide
Use the following criteria to confirm the correct module for your application:
- Step 1 — Confirm part number: Verify the label on the existing module reads 5X00226G02. Note the G-suffix revision (G01, G02, G03) as revisions may differ in minor hardware features.
- Step 2 — Check rack slot assignment: Confirm the slot address and I/O channel mapping in your system’s I/O assignment drawings.
- Step 3 — Verify firmware version: Ensure your OCR 400 controller firmware supports the G02 revision. Contact Konmask if uncertain.
- Step 4 — Assess replacement vs. upgrade: If the OCR 400 platform is approaching end-of-support, evaluate a phased migration to Emerson Ovation or equivalent modern DCS.
- Step 5 — Request a quote: Provide your quantity, required delivery timeline, and any certification requirements when contacting us.

Replacement & Compatibility FAQ
Q: Can the 5X00226G02 replace a 5X00226G01?
A: In most cases yes, as G02 is a later revision of the same module. However, confirm with your system documentation that the G02 revision is supported by your controller firmware version.
Q: Is this module compatible with the Emerson Ovation DCS?
A: No — the 5X00226G02 is designed for the Westinghouse OCR 400 platform. Migration to Ovation requires a full I/O replacement project. Contact us for migration support.
Q: Do you offer tested/refurbished units?
A: Yes. All units are functionally tested. Condition (new surplus, refurbished, or used-tested) is specified in the product listing or quotation.
Q: What is the lead time?
A: In-stock units ship within 1–3 business days. For out-of-stock items, typical sourcing lead time is 2–6 weeks. Contact us for current availability.
Q: Can you provide a datasheet or wiring diagram?
A: We can share available OEM documentation upon request. Email support@konmask.com with your inquiry.
